Under normal operating conditions, the cata-
lytic converter will not require maintenance.
However, it is important to keep the engine
properly tuned to assure proper catalyst
operation and prevent possible catalyst
damage.
NOTE:
Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfunctioning engine operation, a
scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs,
stop the vehicle, turn off the engine and allow it to cool. Service, including a tune-up
to manufacturer's specifications, should be
obtained immediately.
To minimize the possibility of catalytic
converter damage:
Do not interrupt the ignition when the
transmission is in gear and the vehicle is
in motion.
Do not try to start the vehicle by pushing
or towing the vehicle.
Do not idle the engine with any ignition
components disconnected or removed,
such as when diagnostic testing, or for
prolonged periods during very rough idle or
malfunctioning operating conditions.
Cooling System
Coolant Checks
Check engine coolant (antifreeze) protec
-
tion every 12 months (before the onset of
freezing weather, where applicable). If the
engine coolant (antifreeze) is dirty or rusty
in appearance, the system should be
drained, flushed and refilled with fresh
engine coolant (antifreeze). Check the front
of the A/C condenser for any accumulation
of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically
down the face of the condenser.
Damage to the catalytic converter can
result if your vehicle is not kept in proper
operating condition. In the event of
engine malfunction, particularly
involving engine misfire or other
apparent loss of performance, have your
vehicle serviced promptly. Continued
operation of your vehicle with a severe
malfunction could cause the converter to
overheat, resulting in possible damage to
the converter and vehicle.
CAUTION! (Continued)
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam
from your radiator. If you see or hear
steam coming from under the hood, do
not open the hood until the radiator has
had time to cool. Never open a cooling
system pressure cap when the radiator or
coolant bottle is hot.
Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
When working near the radiator cooling
fan, turn the ignition to the OFF mode.
The fan is temperature controlled and
can start at any time the ignition is in the
ON mode.

SERVICING AND MAINTENANCE
230
(Continued)
Cooling System Pressure Cap
The cap must be fully tightened to prevent
loss of engine coolant (antifreeze), and to
ensure that engine coolant (antifreeze) will
return to the radiator from the coolant expan-
sion bottle/recovery tank if so equipped.
The cap should be inspected and cleaned if
there is any accumulation of foreign material
on the sealing surfaces.
Brake System
In order to assure brake system performance,
all brake system components should be
inspected periodically. Refer to the “Mainte -nance Plan” in this section for the proper
maintenance intervals.
Brake Master Cylinder
The fluid in the master cylinder should be
checked when performing under hood
services or immediately if the “Brake
Warning Light” is illuminated.
Be sure to clean the top of the master
cylinder area before removing the cap. If
necessary, add fluid to bring the fluid level
up to the requirements described on the
brake fluid reservoir. With disc brakes, fluid
level can be expected to fall as the brake
pads wear. Brake fluid level should be
checked when pads are replaced. However,
low fluid level may be caused by a leak and
a checkup may be needed.
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubricants”
in “Technical Specifications” for further
information.
WARNING!
Do not open hot engine cooling system.
Never add engine coolant (antifreeze)
when the engine is overheated. Do not
loosen or remove the cap to cool an over
-
heated engine. Heat causes pressure to
build up in the cooling system. To
prevent scalding or injury, do not remove
the pressure cap while the system is hot
or under pressure.
Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal
can result in abnormally high brake
temperatures, excessive lining wear, and
possible brake damage. You would not
have your full braking capacity in an
emergency. WARNING!
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri -
cants” in “Technical Specifications” for
further information. Using the wrong
type of brake fluid can severely damage
your brake system and/or impair its
performance. The proper type of brake
fluid for your vehicle is also identified on
the original factory installed hydraulic
master cylinder reservoir.
To avoid contamination from foreign
matter or moisture, use only new brake
fluid or fluid that has been in a tightly
closed container. Keep the master
cylinder reservoir cap secured at all
times. Brake fluid in a open container
absorbs moisture from the air resulting
in a lower boiling point. This may cause
it to boil unexpectedly during hard or
prolonged braking, resulting in sudden
brake failure. This could result in a colli -
sion.
